As disclosed in the accompanying drawings, F denotes the frame ofthe device and which is substantially in the form of an inverted U with one end member or leg 8substantially straight from end' to end and the opposite or second: end member or leg 33 formed after the fashion of a pistolgrip adapted to be grasped by the hand ofthe user. The members orlegs 8 and 33 together with the intermediate portion of the frame have their longitudinal marginal portions deiinedr by the inwardlydisposed flanges .1 whereby the frame F also constitutes' what may be called'a housing. Pivotally connected, as at 25, between the ,flanges 1, .preferably by outstanding trunnions, is the upper end portion of a lever 9.

The pivotal connection'25 is Vclosely adja-` cent to the'upper end portion of the member 100 or leg 8 of the frame F and the lever 9 is disposed in a general direction toward the opposite end ofthe member or leg 8. The pivoted end portion of the lever 9 is continued by an elongated arm 2 arranged between the side flanges 1 disposed along the intermediate portion 3 of the frame F' and terminates closely adjacent to thel secondmember or leg 33. The vfree end portion of the arm 2 is continued by the downwardly disposed extension 4, the inner edge 4 Aof which being arranged on a downward and outward incline.

A trigger l() is pivotally supported, as at 23, between the flanges 1 at the junction of the intermediate portion or mem-ber 3 of the frame F and the member or leg 33 and at points in advance of the extension 4 but below the arm 2. The pivoted end portion of the triggerv 10l is bifurcated to provide spaced arms 5, each of which having associated therewith a pivotal mounting 23, such as a screw or the like. Y

The arm V2 in, its .swinging movement in connection withl the lever 9 is radapted to swing between the arms 5 and said arms of such length to permit the arm 2 and lever 9 to have desired swinging'action..

The free endl portion of the extension 4'has secured thereto an end portion of a retr'actile coilspring 20, the oppositel end` portion of which being suitably anchored, as at 34, to a lower portion of the member or leg 33, and more particularly theiianges 1 thereof. This spring 2O scrvesxto constantly urge the arm 2 downwardly and the lever 9 in a direction toward the member or leg 8, yet permits the same to readily have swinging movement in the opposite direction. y

rllhe movements of the arm 2 Iand lever 9 are under control of the lever 1() and which lever at a point closely adjacent to the arms v5 thereof is provided with ay rearwardly disposed and upwardly curved pin 22, the free end portion of which having contact with' the inclined edge 4 of the extension 4. In

practice7V the ngers of the hand grasping the member or leg 33 may be readily used to impose requisite pull upon the trigger 10 to force the arm 2 upwardly and the lever 9 rearwardly for a purpose to be hereinafter more particularly referred to.

The member or leg 8 of the frame' F also constitutesa magazine for holding a supply of points and the chamber of said magazine 32 is triangular in cross section to conform to they conguration of said points and. said magazine is open atopposi-te ends.

The cross sectional configuration of the chamber of the magazine 32 is preferablyv of such dimensions to receive a stack of points of the maximum size.,v When it is desired to employ points of smaller sizes an elongated plate of desired thickness is inserted from above within the chamber of the magazine in close contact with the posterior wall of the chamber of the magazine. The upper end portion of such plate 6 is provided with an enlargement or head 6 to facilitate its application or removal, it being understood that when the plate 6 is applied said enlargement or head 6 will be disposed above the upper open end of the chamber of the magazine. Itis also preferred that the points when applied within the chamber of .the magazine 32 be arranged in `a symmetrical column with adjacent points lightly connected by suitable adhesive.

Underlying the lower end of the magazine 32 and member or leg 8 is a magazine plate 13 maintained inv applied or working posi tion through the'medium of the rivets 26 or the like. The forward portion of the plate 13 is provided with a triangular opening 13 which is in register with the lower end of vthe chamber of theA magazine 32 Aand through which the points within the chamber of the magazine 32 are adapted to pass by gravity for successive position indesired alignment with the driver plate 15. The driver plate 15 underlies the applied magazine plate 13 for close contact therewith and the side marginal portions of the plate 15 have secured thereto' by the rivets 27 or the like the forward end portions of the driverv guide members 14. Inter-posed between the overlyingy portions of the yguilde members 14v and the plate 15 are the spacer strips 16maintaine'd in desired position through4 theI medium of the rivets 27 or the like hereinbefore referred to. These guidefmember's 14 extend rearwardly of the driver plate4 15 andare received within the rabbets 7 provided in thelower side marginal portions of the base portion of a driver blockll. These extended portions of the members 1'4 are anchored to the base portion of the driver'block 11 through the medium of rivets 36 or the like. It is to be noted that lthe outer side faces and thev bottom faces of 'the vextended portions of the members 14 received within the rabbets 7 are flush with the side and under faces of the bottom portion of the driver block l1. i 1

The lower portion'of the member 8 is laterally extended in opposite directions, as `at said Y an elongated rod or shankR, the outer or free end portion of which vat all times being slida-bly and snugly received within an opening 33 provided in the lower or free is to be noted that the under face of this ap-y plied block 21 is flush with the adjacent free end of the member or,v leg 33. f

Surrounding the rod or shank R and interposed between the lower portion of the driver block 11 and the lower or free end portion of the member or leg 33 is a spring 17 which,y

upon rearward movement of the driver block 11, is placed under compression to provide means to impart the requisite striking or impact stroke to the driver block 11. A

The lower portion of the driver` block 11 is also provided with the oppositelydisposed and laterally directed pins 35 with each of which is engaged i an' end portion of a retractile spring 18, the opposite end portion'of said spring being secured lto an extended portion 8 of the member or leg 8. As the' driver block 11 is retracted both of the springs 1 8 are placed under tension to facilitate the desired striking or impact stroke of the block.

The driver block 1l extendsv within the frame F a desired distance andits upper portion is provided with a groove or channel 11 of desired depth and extending in the same general direction as the path of travel of the block 11. Pivotally mounted intermediate its ends, as at 28, within the groove or channel 11 is an elongated member or plate 12. The forward end portion of the plate 12 extends in advance of'the'driver block 1l and hasl contacting therewith from below the free end portion of aV leaf spring 19, the oppo` site end portion of .which being secured, as at 29, by a rivet or the like to the forward face of the block 11. This spring V19 serves to constantly urge the extended or forward end portion of the member or plate-12 up wardly, the extent of such movement being" limited by a set screw 30 threaded through the opposite or rear end portion of the member or plate 12 and adapted to have contact with the face of the groove or channel 11. 31denotes a. lock nut engaged with the set screw 30 and contacting with the adjacent portion of the member or plate 12 to effectively hold the set screw 30 in its desired endwise adj ustment.y

l/Vhen the driver block 11 is at the limit of its forward movement the'extended end ofwith said lever 9 extending below the upperv surface of said end of the plate or member 12 as'determinedby the swinging adjustment of the plate or member 12 about its pivot 28 through the instrumentality of the? set screw 30.

As the trigger 1() is drawn toward the member or leg 33 the pistol, as it has been termed, or free end portion of the lever 9 will come in Contact with the adjacent end of the `member or-plate- 12 and force the driver block 11 rearwardly until thel lever 9 passes upwardly out of contact with the adjacent end of the member or plate 12. At this vtime the springsy 17 and 19 hereinbefore referred to will cause the driver block 11 to move toward the member or leg 8 ywith sufiicientspeed to permit the driver plate 15 to have requisite impact.

from the rear `upon the vpoint projected through the opening 13 in the magazine plate 13 and in alignment with the plate 15.I This f action results in such point being driven within a window sash or the like in proper relation with respect to the glasspane. The` extent of retraction'ofthe driver block 11 by the lever 9 is regulated or controlled by the vextent of adjustment of the member or plate 12 about its pivot 28. The lower the front end of the member or plate 12 the shorter thel i stroke of the block 11 and'vicel versa. f

The arrangement of` t-he member or leg 33 or grip, as it may be termed, togetherfwith the springs 17 and 18 results in an effective equalization of the power and in a manner tolkeep the device from jerking or jumping during a working operation and .thus -preventing breakage of glass.

' It is'also to be particularly noted that the device is of such a"construction that makes it extremely light and which in connection with a device of this kind is an important factor.

It is also to be noted lthat thel mounting of the driver block l1l is such as to possess a maximum of strength and that the assembly of such block 1l when `in working position eliminatesV liability of thedriver plate 15 bending or getting out of place and which decided advantage is particularly due to the guide springs 14 and the parts directly associated therewith.

From thef foregoing 'description it is thought to be obvious that a'glaziers point setter'constructed 1n accordance with our 1nvention is particularly well adapted for use` by reason of the convenience. and facility with which it may be assembled and operated, andV it will also beobvious that our invention is susceptible of some change and modification without departing from the principles and spirit thereof'and for this reason we do not wish to be understood as limiting ourselves to the precise arrangement and formation of the several parts herein shown inA carrying applied magazine plate partially underlying said channels, elongated guide members movable through said channels and held therein I by the extended portions of the magazine plate, a driver plate secured to and bridging the space between the forward end portions ofthe guide members, said driver plate underlying the magazine plate, a driver block, means for securing the inner portions'of the Vguide members to the driver block, means forretracting the driver block, and means for imparting an impact stroke to the driver block upon release therefrom of the retracting means.
